Struct Assignment 

pub struct Assignment {
    pub values: HashMap<usize, i64>,
}

A (partial or complete) mapping from variable ids to assigned values.

Fields

values: HashMap<usize, i64>

Internal map: variable index → assigned value.

Implementations

impl Assignment

pub fn new() -> Self

Create an empty assignment.

pub fn is_complete(&self, num_vars: usize) -> bool

Return true when all num_vars variables have been assigned.

pub fn get(&self, var: CspVarId) -> Option<i64>

Retrieve the assigned value for var, if any.

pub fn set(&mut self, var: CspVarId, value: i64)

Assign value to var.

pub fn unset(&mut self, var: CspVarId)

Remove the assignment for var.

pub fn iter(&self) -> impl Iterator<Item = (CspVarId, i64)> + '_

Iterate over all (var_id, value) pairs.

Trait Implementations

impl Clone for Assignment

fn clone(&self) -> Assignment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Assignment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Assignment

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Assignment

impl PartialEq for Assignment

fn eq(&self, other: &Assignment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
